asterisk users - Nov 2003 - CallerID when transfering

Hi,

I have one X100P, one ATA186 with two phones (with CalleID support).

When I receive a call from PSTN, both phones rings and the CallerID is
displayed on both.
I answer to one of them an then transfer the call (unattended) to the other
one using '#' key.
The other phone rings, but no CallerID is displayed?
It is a bug or this is something normal?

Thanks,
Dan
